CIPHER Morning Ritual (Dec 2025)

AI-powered daily planning system that runs on first terminal boot.

Location: ~/.dotfiles/bin/morning-ritual

What it does: CIPHER analyzes your entire context and suggests 12 pomodoros RANKED BY PRIORITY. Pick your top 3 via fzf multi-select.

Context gathered:

• Things.app tasks (Today + Anytime lists)

• Command history patterns
• GitHub notifications, PRs awaiting review
• Obsidian week note + 5 recent docs
• Day/time energy state (weekend vs weekday)

Architecture:

.startup.sh runs on first boot
    ↓
Gather ALL context (Things, calendar, git, Obsidian, GitHub)
    ↓
Send to Claude CLI with CIPHER persona
    ↓
fzf with 12 ranked pomodoros (#01-#12)
    ↓
TAB to multi-select, Enter to accept
    ↓
Selected tasks added to Things inbox

CIPHER personality: Terse, insightful, William Gibson meets Unix philosophy. Dry wit with competence. Geometric symbols: ◆ ◇ ○ ●

Usage:

morning-ritual              # Force run
rm /tmp/morning_ritual/last_run && morning-ritual  # Reset today

AI-Powered Git Commits (Dec 2025)

Location: ~/.dotfiles/bin/ai-commit

Usage: In lazygit, press a key after staging files.

Flow:

Stage files in lazygit (space)
    ↓
Hit 'a' key
    ↓
ai-commit gathers: staged diff, branch name, recent commits
    ↓
Claude returns 3 conventional commit messages
    ↓
fzf with diff preview (60% right pane)
    ↓
Select message, commit executes

Lazygit config: ~/.config/lazygit/config.yml

customCommands:
  - key: "a"
    context: "files"
    description: "AI commit (fzf + Claude)"
    subprocess: true
    command: 'MSG=$(ai-commit) && git commit -m "$MSG"'

Terminal & Multiplexer

Tmux (.tmux.conf)

Minimalist terminal multiplexer configuration:

Visual Design:

• No colors (theme-agnostic)
• Geometric pane count indicators (⚌ ☰ ⚍ ⚏ ☷)
• Centered window list
• Prefix indicator: ◼ (when active)

Key Bindings:

Prefix: C-a
Windows: Alt+h/l (prev/next)
Panes: hjkl (vim-style)
Resize: HJKL (capital letters)
Split: - (horizontal), _ (vertical)

Tmux 2025 Popup Workflows (Nov 2025)

Modern popup workflows that float over your pane layout:

Popups:

• C-a g → Lazygit popup in current directory
• C-a K → Yazi file manager popup
• C-a S → Scratch terminal toggle (persistent)

Pane Capture:

• C-a C-y → Yank entire pane to clipboard
• C-a M-y → Yank last 200 lines to clipboard

Mermaid-ASCII Integration (Sept 2025)

Send ASCII diagrams to tmux panes.

Functions:

• send-mermaid <pane> - Send diagram to pane
• test-mermaid [pane] - Quick test (defaults to 0:6.2)
• setup-diagram-listener <pane> - Auto-refresh display

Critical rules:

• Use multiline syntax (not semicolons)
• Always use -a flag for ASCII-only mode

echo "graph TD
A[Start] --> B[Process]
B --> C[End]" | mermaid-ascii -a > /tmp/diagram.txt
tmux send-keys -t 0:6.2 "cat /tmp/diagram.txt" Enter

The Philosophy

Minimalism as Cognitive Offloading

Every visual element that isn't essential is cognitive load. The monochrome approach keeps your visual cortex available for actual work.

Automation as Anxiety Reduction

AI handles triage. Email filtering removes uncertainty. The startup dashboard prevents "what did I forget?" anxiety.

Immediacy Over Perfection

Shortcuts prioritize immediate access over complete functionality. Small, frequent commits with "good enough" messages beat perfect commits that never happen.

Theme Agnosticism as Future-Proofing

Monochrome and geometric symbols remain functional regardless of OS design changes. Decoupled from aesthetic fashions.

Intelligence at the Edges

AI handles pattern recognition and filtering. Human decision-making stays human. The system never makes choices for you.
